Installing the spare tire
The spare tire is designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of this
manual.
1. Clean any mud or dirt from the surface be-
tween the wheel and hub.
2. Carefully put the spare tire on and tighten
the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel
nuts alternately and evenly as illustrated until
they are tight.4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated (
sA,sB,sC,sD).
Lower the vehicle completely.
WARNING
cIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
cDo not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
cRetighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque:
80 ft-lb (108 N·m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each lubrication interval.Adjust tire pressure to the COLD pressure.
COLD pressure: After vehicle has been
parked for three hours or more or driven
less than 1 mile (1.6 km) .
COLD tire pressures are shown on the tire
placard affixed to the driver’s door center
pillar.
5. Securely store the flat tire in the vehicle.

6. Clean and reinstall the drain plug and a new
washer. Securely tighten the drain plug with
a wrench. Do not use excessive force.
Drain plug tightening torque:
22 - 29 ft-lb (29 - 39 N·m)
7. Refill engine with recommended oil through
the oil filler opening, then install the oil filler
cap securely.
See “Capacities and recommended
fuel/lubricants” in the “Technical and con-
sumer information” section of this manual for
drain and refill capacity.
The drain and refill capacity depends on the
oil temperature and drain time. Use thesespecifications for reference only. Always use
the dipstick to determine when the proper
amount of oil is in the engine.
8. Start the engine. Check for leakage around
the drain plug and oil filter. Correct as re-
quired.
9. Turn the engine off and wait more than 10
minutes. Check the oil level with the dipstick.
Add engine oil if necessary.
CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and apply
the parking brake.
2. Turn the engine off.
3. Place a large drain pan under the oil filter.
4. Loosen the oil filter with an oil filter wrench
by turning it counterclockwise. Then remove
the oil filter by turning it by hand.

Platinum-tipped spark plugs
It is not necessary to replace platinum-tipped
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance schedule, but do not reuse
the spark plugs by cleaning or regapping.
cAlways replace spark plugs with recom-
mended or equivalent ones.
1. Remove the engine cover.
2. Disconnect the ignition coil connectors. Re-
move the ignition coil bolts.
3. Disconnect the spark plug cables from the
spark plugs.When disconnecting, always hold
the boots — not the cables. Mark all
cables to identify their original loca-
tions.
4. Remove the spark plugs with a spark plug
socket.
The plug socket has a rubber seal that holds
the spark plug so it does not fall when it is
pulled out. Make sure each spark plug is
snugly fitted into the spark plug socket.
5. Fit the new plugs, one at a time, into the
spark plug socket and install them.Use
only the specified spark plugs.Turn
each plug several full turns by hand, then
tighten with the spark plug socket to the
correct torque. Do not overtighten.
Spark plug tightening torque:
14 - 22 ft-lb (20 - 29 N·m)
6. Holding the boot, reconnect each high ten-
sion cable to its proper spark plug by push-
ing it on until you feel a snap.
7. Iinstall the ignition coil bolts.
Ignition coil bolt tightening torque:
33 - 44 in-lb (3.8 - 5.0 N·m)
Connect the ignition coil connector.
8. Install the engine cover.The air cleaner filter should not be cleaned and
reused. Replace it according to the maintenance
intervals shown in the “NISSAN Service and
Maintenance Guide.” When replacing the filter,
wipe the inside of the air cleaner filter housing
and the cover with a damp cloth.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires every
7,500 miles (12,000 km) .
See “Flat tire” in the “In case of emergency”
section of this manual for tire replacing proce-
dures.
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque:
80 ft-lb (108 N·m)The wheel nuts must be kept tightened to
specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation interval.
WARNING
cAfter rotating the tires, check and ad-
just the tire pressure.
cRetighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
cDo not include the spare tire in the tire
rotation.
cFor additional information regarding
tires, refer to Important Tire Safety In-
